ASINH DAX Function (Math and Trig)
Returns the inverse hyperbolic sine of a number. The inverse hyperbolic sine is the value whose hyperbolic sine is number, so ASINH(SINH(number)) equals number.
Syntax
ASINH ( <Number> )
| Parameter | Attributes | Description |
|---|---|---|
| Number |
Any real number. |
Return values
Scalar A single decimal value.
Remarks
Returns the inverse hyperbolic sine of a number.
Examples
-- SINH, COSH, ASINH, ACOSH, TANH, ATANH, COTH, ACOTH
-- are the standard hyperbolic trigonometrical functions.
--
-- Where required, the arguments are specified in radians.
